IE 8 InPrivate Filtering
UPDATE: If you are looking for instructions on how to set IE 8 inPrivate Filtering on by default, please go here: http://www.ruddwire.com/reviews/2009/05/07/ie-8-inprivate-filtering-on-by-default/
IE8’s most notable new feature is “inPrivate Filtering”: this is a domain filtering service that is very easily turned on by a button at the bottom of the window, in the status bar. With one click, the browser blocks content served by third party domains.
In other words, you read content at latimes.com, and latimes.com tries to show you ads that are served by advertising.com. The advertising.com ads will be blocked when you turn on inPrivate Filtering. Not right away. The default setting is that you have to visit 10 websites that call ads from advertising.com before ads are blocked. If you turn on inPrivate Filtering whenever you surf, then the most popular adservers and analytics domains will quickly reach 10 hits and be blocked. And they’ll be blocked every time you turn on inPrivate Filtering.
